CARE in human VEGFA 3′-UTR is targeted by miRNAs. (A) Schematic of human VEGFA 3′-UTR elements. The full-length VEGFA 3′-UTR (top) is expanded to show elements in the HSR (middle) and the sequence of the CARE and seed regions of predicted CARE-binding miRNAs (bottom). (B) CARE-binding miRNA candidates. (C) CARE-binding miRNAs inhibit expression of reporter bearing human VEGFA HSR. FLuc reporter constructs in pcDNA3 vector bearing either wild type (left) or mutant (right) CARE in the HSR were transfected into HEK293T cells with CARE-binding miRNA candidates (miR-297, -299, -567, and -609), miR-control (Cont.), negative controls (miR-410 and -369), and with RLuc-expressing pRL-SV40 vector as internal control. Relative Luc levels were measured after 24 h and expressed as percentage of control. Results are expressed as mean±s.d., for n=3 independent experiments. An asterisk (*) indicates a significant difference, P<0.05, two-tailed t-test.
